SPECIFICATION forming part of Letters Patent No. 442,742, dated December 16, 1890.

Application filed September 5, 1890. Serial No. 363,996. (No model.)

To a/ZZ whom, it may concern:

Beitkuowu that I, FRANK. C. W1LsEY,aciti zen of the United States, residing at Bentonville, in the county of Benton and State of Arkansas, have invented certain new and useful Improvements in Ice-Cream Freezers; and I do declare the following to be a full,.clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specifica- My invention relates to certain new and useful improvements 1n ice-cream freezers; and

it consists in the construction, combination,

and arrangement of the several parts of which it is composed, as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, in which corresponding parts are designated by similar letters, Figure l is a side elevation of my invention, parts thereof being broken away. Fig. 2 is an end elevation thereof, partly in section. Fig. 3 is a perspective View of the scraper.

The base A has at each end thereof an upright A', which carry the cross-piece A2 on their upper ends, the upper ends of the inclined braces As (the lower ends of which are over the uprights A) carrying the post A4.

The double lever B is pivoted at its center in the upper end of the post A4, and has attached to its opposite ends the cord B', the central portion of which passes around the barrel B2, carried by the vertical shaft B3, the upper end of which is'housed in the recess a in the base of the post A4, while the lower end is within the notch a in the center of the cross-piece A2. One end of the cord B is secured to the lever B by means of the clamp b, which is provided with a thumb-nut b', thereby permitting the cord to be tightened by nnscrewing the clamp and pulling the cord therethrough, when the clamp may be again tightened. It will be seen that by rocking the lever B by means of the handles b2 upon its end the barrel B2 will be rotated first in the one direction and then in the other, and it will also be seen that as the cordB passes from the opposite pulleys b3,

carried in the braces A3 to the barrel B2 in a straight line, that the elasticity of the cord will tend to retain the latter in the position shown in full lines in Fig. l, although the shaft B3 is so constructed as to be capable of being raised, it then having the position shown in dotted lines in the said figure. The

'bottom of the shaft B3 has a squared recess b4 therein, which is adapted to receive the heads of theposts of the freezer or dasher, as will be hereinafter described.

The base Ahas at eachend Ithereof, but Within the uprights A', the arc-shaped plates C, be# tween which the vessel D is held, which vessel may be either the outer vessel of the freezer or the churn. In the former case the vessel has a bridge e secured upon its bottom, the said bridge having a hole therein, in which rests the stud c2 upon the cap C', in which rests the inner vessel C2 of the freezer. The upper part of the vessel C2 is grasped on its sides by the arc-shaped clamps C3 upon the lower end of the forked arms C4, which are adapted to be drawn together at their bottom by the screw and nut c passing therethrough below their upper ends, thus holding the vessel C2 securely. Cams c2 are secured to the inner sides of the said arms and are adapted to be rotated, engaging the cover C5 of the vessel C2, forcing the former securely intoits seat. The upper ends of the arms C? are arcshaped and are upon the opposite sides of, y

the post C, which has a vertical slot C3 therein, through which passes a bolt secured to onev of the arms C, a thumb-nut c4, bearing upon the opposite arm, being provided in order to clamp the said post within the said arms at any desired position, thereby permitting the distance from the stud c to the squared head c5 upon the top of the post CG to be varied, if desired, the said head e5 being adapted to fit within the recess b" in the shaft- A scraper CT is contained within the vessel C2, it being of the same width as is the interior diameter of the vessel, and having its scraping-edges bent in opposite directions. A stem CS is secured to the top of the scraper at its center and passes through the cover C5, it being bent upon the outside thereof, the'crank Cf" of the said stem C8 projecting above the cover to the outside of the vessel C2. It will thus be Ico or less tightly by the freezing-mixture contained Within the vessel C and prevented from moving freely While the vessel C2 is being rotated first in the one direction and then in the other by the mot-ion imparted to the barrel B2, thus caus'ng the scraping-edges ci on the scraper CT to scrape off the frozen cream from the interior of the vessel C2 as it may be formed, keeping the metallic su rfaee thereof clear and causing the contents thereof to freeze the quicker.

It Will be seen that the post CG may be readily removed and replaced by liftingthe shaft B3 to the position shown in dotted lines in Fig. l, thus disengaging the head e5 and the recess c4, it being as readily replaced by putting itin position and permitting the shaft B3 to be drawn into its normal position bythe tension of the cord B, or vice versa. It will also be seen that by means of the slot c3 and thumb-nut c4 the post C6 may beso raised as to cause its head c5 to be at a proper height to be engaged by the recess b4, irrespective of the size of the vessel C2. f

Theoperation of my invention will be readily understood from the foregoing, and therefore needs no further description here.

Having thus described my invention, what Il claim is l. In an icc-cream freezer, the combination, with an ice-receptacle, ot a freezing-vessel contained therein, a scraper within the said vessel, having a handle projecting beyond t-hev outside of the said vessel and adapted to be held by the ice, and means for alternately turning the said vessel in opposite directions, as described.

2. The combination, with a post having a longitudinal slot therein, of bifurcated arms, one upon each side of the said post, a bolt passing through the said slot and holding the said parts adjustably together, arc-shaped clamps upon the base of the said arms,aves sel between the said clamps, a cover on the top ot the said vessehcams upon the said arms bearing upon the said cover, an'd a scraper Within the said vessel, having a crank secu red thereto and projecting on the outsidev of the said vessel, as described.

In testimony Whereofl afiix my Signat ure 1n presence ot two Witnesses.
